[vtkusers] Move arrow in the direction of point normal

[Alex Malyushytskyy]

Correctly asked question is 50% of the answer.
Your question does not provide details on which data types your are working

There is no such class in vtk as ArrowObject.

If you work with vtkPolyData which represent your arrow, you need to define
transformation which will  adjust orientation of your polydata and
translate it to desired location.

Useful example might be:
